Designed for engineers working with I, box and tub girder bridges with complex curvature and skew alignments, 4D BRIDGE pLT is LARSA's entry level package within the BRIDGE SERIES Suite. Featuring LARSA's powerful staged construction analysis engine in addition to LARSA's bridge specific tools, such as influence surface based live load and Bridge Path Coordinate Systems, 4D BRIDGE pLT delivers high end features without the high end price tag commonly associated with advanced finite element analysis software.

LARSA 4D's Steel Bridge Module uses a wizard-like interface to simplify 3D model generation for complex I, box, and tub girder bridges, while providing fully integrated AASHTO compliant code check and load rating tools, along with the ability to move beyond typical grillage analysis to utilize influence surface based live load.

LARSA's Section Composer is a graphical companion tool for modeling arbitrary sections for use in LARSA 4D. Section Composer supports standard, parametric, nonprismatic, and custom shape sections
